将res res对象传递给socket.io？

Question

I am a little confused how I can interact with the socket when I need to pass in data from my routes file. I have the standard setup using node.js, express, mongodb etc.

I'll run my socket.io logic inside server.js, and I include the routes.js inside that file.

var routes = require('./app/routes');

In this case I need to run some io.sockets inside my routes.js file.

My question is what is a good way to do this? I could run that specific route inside server.js but that gets messy. If I were to use sockets in my routes.js do I need to re-require

var io = require('socket.io').listen(server);

That means I need to create a new http server object, and I don't like that since I am requiring this file in server.js, this seems like a counter-intuitive move to me.

So how do I make a request to the server and pass for example a user name?

Example:

app.get('/profile', isLoggedIn, function(req, res) {

    res.render('profile', { user : req.user });

    io.sockets.on('connection', function (socket) {
        console.log(socket);
            console.log(req.user); // Here I have access to the user and can pass that around in                        my sockets
    });

});

I am also using route middleware, so I'd like to keep that in my routes.js, IDK I am just confused what I should do, hopefully someone understands my angle here?

Edit:

What about passing something into the routes?

routes.initialize(app, passport);

You can get the req and res objects directly in the socket by invoking socket.request (a Getter function which is available via __proto__ ). See docs .

I was then able to find req.user in socket.request.client.user .
